“Strikeforce: Diaz vs. Daley” takes place April 9 at Valley View Casino Center in San Diego, and the main card airs live on Showtime.

The event is co-headlined by a welterweight title fight between reigning champion Nick Diaz and Paul Daley, as well as lightweight champ Gilbert Melendez vs. Tatsuya Kawajiri.

Takaya returns to the U.S. for the first time since a two-fight stint with the WEC in 2008. Since then, the Japanese fighter has competed exclusively in DREAM, where he posted a runner-up finish in the organization’s 2009 featherweight grand prix. He also defeated then-DREAM champ Bibiano Fernandes for the title in his most recent fight. He’s now won three straight and six of his past eight.

He faces another Strikeforce newcomer in Peralta, who enters the promotion on the heels of a six-fight win streak in the California-based Gladiator Challenge organization. All of the wins have come via stoppage, though his opposition has a combined 5-11 record. However, Peralta does own an early-2009 victory over current Tachi Palace Fights flyweight champion Darrell Montague.
